Since I don't use it that often anymore and need the money, I'm selling my X-Particles 4 license. It's the whole commercial edition and not some kind of education edition.
Price: $499 (new price at Insydium is $718.69)
I'm open to any offers. Please contact me via PM. I have an eBay account with over 400 positive feedbacks.
For more questions, don't hesitate to contact me.
